This invention relates to novel hindered cycloaliphatic monoisocyanates of the general formula: ##STR1## wherein R.sub.1 -R.sub.7 are members of the group consisting of H, alkyl, cycloalkyl, aryl, alkaryl, aralkyl or mixtures thereof wherein the alkyl groups contain 1-18 carbon atoms, the cycloalkyl groups contain 4-8 carbon atoms and the aryl groups contain 6-14 carbon atoms with the proviso that where R.sub.3 is a group member other than H, R.sub.1, R.sub.2, R.sub.4 and R.sub.5 can be H and with the further proviso that where R.sub.3 is H at least two of R.sub.1, R.sub.2, R.sub.4 and R.sub.5 are group members other than H and x is 1 to 7. Other novel dihindered intermediate compositions include aliphatic monoamines.
本发明涉及新型受阻环脂单异氰酸酯,其一般式为:##STR1##其中,R.sub.1-R.sub.7是H、烷基、环烷基、芳基、烷芳基、芳基烷基或其混合物的成员,其中烷基含有1-18个碳原子,环烷基含有4-8个碳原子,芳基含有6-14个碳原子,但其中R.sub.3是除H以外的组成员时,R.sub.1、R.sub.2、R.sub.4和R.sub.5可以是H,并且在R.sub.3是H的进一步规定中,至少有两个R.sub.1、R.sub.2、R.sub.4和R.sub.5是除H以外的组成员,x为1至7。其他新型的双受阻中间体组成物包括脂肪族单胺。
